We can use this idea inside C code,
then, we need decide to use it or not use it somehow ?
We can do everything in C code, I have no concern about it.
But, my main concern is that how to decide this switching from DT file.
How to decide to use this "data table" ?
Does this mean you can accept new compatible ?

     compatible = "simple-audio-card"; # normal simple-card

     compatible = "soc-audio-card";    # special sound card
                                       # we use DPCM this time
